What Causes the Windshield to Not Be Cleaned Properly?

[AshlynRose]

The reasons why the windshield cannot be cleaned properly are: 1. The wiper blades are aged; 2. The glass surface is corroded. A wiper is a blade structure installed in front of the windshield, composed of a motor, reducer, four-link mechanism, wiper arm spindle, and wiper blade assembly. Its function is to remove rain, snow, and dust that obstruct the view on the windshield. The method for removing and installing the wiper is: 1. Lift the metal wiper arm from the windshield and keep it stable in a position perpendicular to the windshield; 2. Press the buckle to remove the old wiper blade, separate it from the metal arm, then insert the new wiper and rotate it until the hook snaps into place and is secured; 3. Place the wiper back onto the windshield.

I've been driving for over ten years and have seen plenty of issues with windshield wipers not cleaning properly. Most of the time, it's due to aging or deformed wiper blades, where the rubber hardens or cracks, causing the wipers to skip and leave streaks or blurry spots. Sometimes, an oily film builds up on the glass—especially after highway driving or rain—where tire spray deposits grease and bug residue, making reflections more hazy under sunlight. Uneven pressure or misalignment of the wiper arms, or loose springs, can also lead to uneven wiping. Another common issue is when the washer fluid is too diluted or nearly empty, leaving the windshield foggy and uncleaned. I make it a habit to replace wiper blades every six months, opting for high-quality ones that last longer. For daily cleaning, I use dedicated glass cleaner to remove stubborn stains. In winter, I avoid scraping frozen areas forcefully to prevent damage. Taking care of these small details ensures clear visibility and safer driving—no one wants an accident from poor visibility.

When I first started learning to drive, I was troubled by the wipers not cleaning properly. Probably the wiper blades were worn and had burrs, making a clicking sound and leaving marks when wiping. There was a layer of sticky oil stains, insect remains, or tree sap stuck on the windshield that couldn’t be wiped off, especially after driving in the rainy season, leaving a mess. The wiper fluid was too diluted or dried up, making cleaning ineffective. Additionally, the wiper arms were improperly installed and misaligned, affecting the fit. I check the wiper blades every three months, gently wiping them with a damp cloth to maintain elasticity. When replacing them, I choose silicone material for better anti-aging properties. In summer, I avoid parking under direct sunlight to prevent deformation. I usually add special wiper fluid to enhance lubrication. Paying attention to these details makes driving much clearer.

I usually enjoy studying vehicle maintenance. Windshield wipers not cleaning properly is often due to aging or cracked rubber blades failing to wipe thoroughly. A thick buildup of oil film and dirt on the glass surface causes glare and a foggy appearance. Weak springs or misaligned angles in the wiper arms lead to uneven wiping. Poor-quality or insufficient wiper fluid leaves water streaks. It's recommended to replace wiper blades every six months to ensure good contact. Use oil film remover to clean the glass and improve light transmission. Check wiper pressure to avoid looseness. Choose antifreeze-formula wiper fluid to prevent freezing in winter. Maintain clear and safe visibility for driving.

When traveling with my family, I'm always concerned about blurred windshields affecting safety. The main issues are hardened or damaged wiper blades leaving streaks after wiping, and oil film buildup from accumulated grime obstructing visibility. This becomes particularly problematic in winter when frost and ice make cleaning less efficient. The recommended replacement cycle is generally once a year, ensuring correct size matching during installation. For daily maintenance, use glass cleaner to wipe away stubborn stains. Keep the wiper fluid reservoir full to prevent dry operation damage. When parking, lift the wipers to prevent adhesion or aging. These measures ensure a comfortable and safe driving experience for the whole family.
